While not directly related to the radio output, the survey area population shows how many people live in the survey area that the above figures are based on. Sudden changes to this figure normally represent a change in the survey area, which is requested by stations themselves, reflecting a change in transmission or programming, and will affect the above figures. Otherwise, a slow growth reflects the growth in UK population.

We use the largest available reported area for each station in RAJAR. Hold your mouse over the graph to discover what the surveyed name was. Where a station is surveyed across multiple areas, individual areas may achieve higher figures. Examine trends with care: numbers are not always comparable.

From the US?

Howdy! We don’t do AQH figures in the UK; but our figure for weekly ‘reach’ is roughly the same as your weekly ‘cume’. TSL is similar to our ‘hours per listener’ figure. And, a TSA in the US is the same as a TSA here.Of note: UK figures are based on a full 24 hour day, and a 7 day week - and the above figures measure radio listening on all platforms, including our digital radio and internet platforms. We don’t quote AQH figures.
